Tropes and References

When Hiroyo tells the Akibarangers they need to be in Akihabara to transform, Nobuo notes that they are 'local heroes', a reference to the Sentai-esque local heroes.

As Mitsuki prepares the team for her three-day absence, Nobuo notes that a three-man Sentai with only two members hasn't occured since Sun Vulcan, when Ryuusuke Oowashi went to NASA and Takayuki Hiba hadn't shown up yet to replace him as VulEagle.

This reference is actually wrong, as Takayuki appeared before Ryuusuke's departure, and the latter was in fact there to pass the torch to the former.

Upon seeing a group of people, which include men dressed as women, entering an old and suspicious looking building (which turns out to be a "Cross-Dressing Cafe"), Nobuo is reminded of Tokusou Sentai DekarangerEpisode. 26: Cool Passion, where to investigate an illegal fighting ring, the Dekarangers went undercover to visit their underground arena, during which, Tetsu dresses up as a woman.

During a moment where Hakase is bored while Kozukozu is cleaning the helmets, she plants herself right between Red Falcon and Red Turbo; Liveman is considered the last Sentai of the Showa era and Turboranger the first of Heisei, thus the demarcated boundary she unintentionally creates.

Nobuo spots that the Maskman Deluxe Chogokin Great Five worth 180,000 yen is gone. Its place in the shop window has been taken by a figure from "Gavian".

During the fight, Akiba Red notes that in official Sentai, this is the time where the missing member would show up to save their team. He mentions Choudenshi Bioman episode 10, Goodbye Yellow, remembering that sometimes in official Sentai, characters only show up after having transformed already. He suggests that they could Akiba Blue to appear despite Mitsuki's absence, the monster grants them his wish.

Technically the reason Yellow Four had appeared in costume in this episode is due to her actress, Yuki Yajima, already leaving the show, thus making this the character's final episode. Mayumi Tanaka is her voice actress in this matter.

When this Akiba Blue attacks her teammates, Nobuo mistakenly confuses this for a "brainwashing episode".
